 To mitigate this value extraction on RETH and WSTETH branches, the system uses the maximum of a market price and a canonical price in redemptions. This mitigates oracle lag arbitrages by giving the redeemer the "worst" price at any given moment.
 
-However, this only applies if the delta between market price and canonical price is within the oracle deviation threshold (1% for WSTETH, 2% for RETH). If the difference is greater, then the normal primary pricing calculation is used - a large delta is assumed to reflect a legitimate difference between market price and canonical rate.
+The trade-off of this solution that redemptions may sometimes be unprofitable during volatile peroods with high oracle lag. However, as long as redemptions do happen eventually and in the long term, then peg maintenance will hold.

 However, we don’t expect oracle frontrunning to be a significant issue since these LST-ETH feeds are historically not volatile and rarely deviate by significant amounts: they usually update based on the heartbeat (mininum update frequency) rather than the threshold.
